Abstract

"BROCA PARA PERFURAçãO PROFUNDA". O objetivo da presente invenção é prover uma broca para produzir uma perfuração profunda que não produza curvaturas na perfuração durante o corte. Um corpo de perfuração (1) é provido com um par de gumes cortantes em espiral (3). Os gumes cortantes (3) são espaçados em cerca de 180<198> entre si em torno de um núcleo (1a) da broca e a linha da borda (3a) de uma parte saliente dos gumes cortantes (3) é rebaixada na direção de um núcleo (1a) da broca. Quando a dimensão externa da broca é 7, 4 mm, um ângulo entre a linha da borda (3a ) e uma linha perpendicular ao núcleo (1a) é de 5<198> e a espessura do núcleo (t) é de 2,96 mm. Adicionalmente, a broca é provida com uma parte guia (4) para evitar a curvatura no caso de uma operação de corte. A parte guia (4) é provida na lateral extrema na mesma circunferência na qual as extremidades externas dos gumes cortantes (3, 3) passam."DRILL FOR DEEP DRILLING". The object of the present invention is to provide a drill to produce a deep bore that does not produce bends in the bore during cutting. A piercing body (1) is provided with a pair of spiral cutting edges (3). The cutting edges (3) are spaced about 180 <198> from each other around a core (1a) of the drill bit and the edge line (3a) of a protruding part of the cutting edges (3) is lowered in the direction of a core (1a) of the drill bit. When the outer dimension of the drill bit is 7.4 mm, an angle between the edge line (3a) and a line perpendicular to the core (1a) is 5 <198> and the core thickness (t) is 2.96 mm Additionally, the drill bit is provided with a guide part (4) to prevent bending in the event of a cutting operation. The guide part (4) is provided on the extreme side in the same circumference at which the outer edges of the cutting edges (3, 3) pass.
